I may be wrong, but the only difference between SERIN and HSERIN is one is handled by software, the other by hardware. But the actual signal is identical, bluetooth shouldn't be able to know or care how it was generated.

Multicalc, you need a DLL possibly. It's in that thread. It works on my XP and WIN7 machines. You REALLY want to get this tool working, it does other things as well as the USART settings.

If an Arduino can do something, I don't see a reason why a PIC couldn't do it.
